Right off the bat it clearly says NAC and Bucillamine are gangbuster ways to fight the Covid crud and other viruses..
"The environmental redox state is an important factor for enveloped viruses' life cycle. The thiol–disulfide balance plays an important role in receptor recognition by the SARS-CoV-2 spike (S) protein. Given that a correct protein conformation is required for protein function and that disulfide bonds are often crucial both for structural stability and conformational changes, it is not surprising that the reduction of the disulfides into sulfhydryl groups in the receptor binding domain (RBD) seriously impairs the binding to ACE2.
1,2 Thus, manipulation of the redox status of the cysteine-rich glycoproteins in the virus envelope can influence viral cell entry.
Cleavage of disulfide bonds by thiol-reducing compounds can efficiently weaken viral binding and prevent SARS-CoV-2 infection"
